Qualis is completely dedicated to client satisfaction. All of our team members are fully employed, punctual and knowledgeable, helping make us one of the most trusted companies in the industry

By working with the best boilers and employing the most experienced personnel, we are able to deliver quality, long-lasting heating solutions for all our customers.

And Most Importantly - We're Proud To Be Gas Safe Registered

We're Gas Safe registered and all of our engineers are all highly trained to work on gas appliances.
Badly fitted and poorly serviced gas appliances can cause gas leaks, fires, explosions and carbon monoxide poisoning. Every year thousands of people across the UK are diagnosed with carbon monoxide poisoning. It is a highly poisonous gas that can kill quickly with no warning, as you cannot see it, taste it or smell it. By ensuring you only hire Gas Safe registered engineers, you take care of your gas appliances properly and in turn, you’re taking care of your home and your loved ones.

I had my 23 year old boiler changed for a new one with smartphone app control. From start to finish I had excellent customer care and therefore very satisfied with the job.
